ABSTRACT:
Separators are prevented from being moved from a correct position before completion of soldering. After calking portions31a,32a,43are plastically deformed and the separator31, 32are mechanically fixed on a header tank40by calking, the separators31, 32are coupled to the header tank40by soldering. Thereby, as the separators31, 32are prevented from being moved from the correct position with respect to the header tank40before completion of soldering, it is possible to prevent defects in soldering where gaps are created in coupled portions.
